SEPULVEDA-VAZQUEZ, Jerónimo et al. The importance of secondary metabolites in the control of gastrointestinal nematodes in sheep with emphasis on Yucatán, Mexico. J.Selva Andina Anim. Sci. [online]. 2018, vol.5, n.2, pp.79-95. ISSN 2311-2581.

The use of plants rich in tannins (PRT) with anthelmintic properties (AH) is an alternative for the control of gastrointestinal nematodes (NGI) in species of cattle interest. The attention in plants with these properties is mainly due to the appearance and extension of parasitic populations resistant to anthelmintics. Recently, in Yucatan, the effect of AH from plant extracts on Haemonchus contortus eggs has been reponed by the hatching inhibition test. Among the main plant species with AH properties are ethanolic and hexane extracts, mainly from the foliage of Lysiloma latisiliquum, Laguncularia racemosa, Rizophora mangle and Avicennia germinans, Theobroma cacao and Coffea arabica. However, it has recently been observed that legumes are an important source of secondary metabolites such as Leucaena leucocephala, Lysiloma latisiliquum, Acacia cornígera and Mimosa bahamensis. The evidence shows that the secondary metabolites that contain some forage legumes affect various biological processes of the gastrointestinal nematodes of ruminants, so it could be an alternative for the control of helminths in the production of small ruminants.
